The M574 Digital Storage Oscilloscope is part the ETC Measuring Lab 3 (EML3) family. It is a dual-channel USB oscilloscope compatible with USB 2.0 and USB 1.1 interface. The scope is connected to a computer using standard USB cable and is powered through USB, so no external power supply is needed. That makes it extremely portable, given its size of just 165 x 111 x 35 mm (excluding connectors and feet). The maximum power consumption of only 2.25W makes it exceptionally usable with battery-powered notebooks.
The device inputs are accessible via BNC connectors and are compatible with standard probes (with minimum of 32 pF compensation range). Internal storage (1M per channel) is used as a fast data buffer to store a measured waveform.
The software in the M574 package provides you with the possibilty to fully operate the device. It works in Windows 98SE/Me/2000/XP/Vista. The tooltip help makes the software easy to learn. Updates to the software are available free of charge. All standard features of modern DSOs (hold acquisition process, hold-off, zoom etc.) and many more (saving/loading the waveforms for future use, export to clipboard, printing the results together with scope settings) are available.
The fast data transfer offers extremely rapid display refresh (creating the impression of an analog instrument).
Four standard acquisition modes (AUTO, NORMAL, SINGLE, MANUAL) are available. The trigger event is created by a dual-level triggering system equipped with a digital pulse length filter and event counter on each level. The channel A, channel B and external trigger input can be activated as a triggering system source. The threshold of the channel A and channel B triggers is settable for the whole range of the scope screen. The threshold of the external trigger is fixed to about 1.5V and is TTL and CMOS compatible. This sophisticated triggering system allows displaying waveforms with very complicated trigger events (e.g. selected row of the video signal).
The time base in 1:1 display mode (no zoom) is settable from 5ns/div to 100ms/div in sequence of 1-2-5. It is possible to set the time base from 625ps/div to 204.8s/div using different zoom settings.
The Roll Mode software package will turn the oscilloscope into datalogger with sampling rate from 50S/s to 5Ms/s in USB 2.0, or 50S/s to 250kS/s in USB 1.1. Measurements are written to your hard disk automatically, so the amount of data measured is limited only by your drive's capacity. Measurements are displayed in real time in the Acquisition window; stored data can be viewed with the Roll Mode Viewer application or exported for analysis in third-party applications.
Optional Software Add-on The optional Development Kit is an API allowing you to add control functions for the scope in your own software applications. It works in Windows 98SE, Me, 2000, XP and Vista. It comes with descriptions and examples of all libraries written in Inprise Delphi, Inprise C++ Builder, Visual C++ 6.0, Visual Basic 6.0, C# .NET and Visual Basic .NET.
